Correct Answer: Option A) 1 and 2
The Ravi River is one of the five major rivers of Punjab in the Indian subcontinent.
It is the smallest river of Punjab - True. The Ravi River is indeed considered the smallest among the five rivers of Punjab (Sutlej, Beas, Ravi, Chenab, and Jhelum) in terms of its flow volume and length within Punjab.
Harappa is located on its banks - True. Harappa, one of the most important archaeological sites of the Indus Valley Civilization, is located on the left bank of the Ravi River in Punjab, Pakistan. This ancient city flourished between 2600-1900 BCE.
It merges directly with the Indus River without joining another river - False. The Ravi River does not directly merge with the Indus River. It first joins the Chenab River, which then joins the Sutlej, before the combined waters flow into the Indus River. This tributary pattern is part of the larger Indus River system.
